The Wright brothers explain that the plane fell at a(n) _____ angle.

a. right
b. acute
c. obtuse
d. oblique

Answer :

Final answer:

The correct term describing the angle at which the plane fell according to the Wright brothers is an oblique angle. The midsagittal plane divides an animal into equal right and left portions, and the ideal launch angle for a projectile to achieve maximum distance is 45°.

Explanation:

The student's question refers to the angle at which a plane may have fallen according to the Wright brothers. Looking at the answer choices provided, the correct answer choice for the angle a plane fell at would be an oblique angle (option d).

Now, addressing the reference information:

A plane that divides an animal into equal right and left portions is called a midsagittal plane (option b).

The optimum angle at which a projectile should be launched to cover the maximum distance is 45° (option b).

When a box sits on an inclined plane, the perpendicular component of the box's weight is at its maximum when the angle of incline is 90° (option d).

For a projectile, the range is equal to zero when the angle is 90° or 0° (option c).

On an inclined plane, the expression for the component of an object's weight force that is parallel to the incline is W∥ = wsinϴ (option b).
